Solution Overview

Problem

Existing electronic cigarettes with oval cross sections face issues such as high risk of mouth burning due to the vaporizer's proximity to the mouthpiece, inadequate separation of impurities and steam, and inconvenient disassembly of components.

Innovation Solution

An electronic cigarette design featuring a vaporizer positioned far from the mouthpiece, creating a long vapor flow channel and using a snap joint connection between the vaporization and control assemblies for easy assembly and disassembly, with a bell-mouth structure for hermetic sealing and a continuous vapor flow pathway.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the vaporizer is arranged inside the oil storage portion at the proximal end of the mouthpiece, then the structure is compact, but the risk of mouth burning increases due to high temperature vapor directly reaching the user

Engineering Contradiction:
Improvestructural compactnessVSAvoidmouth burning risk
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent extends the vapor flow path in the longitudinal dimension by positioning the vaporizer at the distal end rather than the proximal end, creating a longer vaporization channel that allows vapor to cool before reaching the mouthpiece, thus resolving the contradiction between compactness and thermal safety

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If the vapor flow channel is too short after vaporization, then the device structure is simplified, but impurities and steam cannot be completely separated leading to undesired taste

Engineering Contradiction:
Improvevapor flow channel structureVSAvoidvapor quality and taste
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the internal structure by introducing a partition wall that divides the oil storage portion into separate regions, creating distinct zones for vapor generation and vapor cooling/separation, which improves vapor quality without significantly increasing overall device complexity

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the vaporizer, copper part and vaporization rod need to be demounted many times, then component replacement is possible, but it is not convenient for the user to use

Engineering Contradiction:
Improvecomponent replaceabilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges the vaporizer, copper part, and vaporization rod into a single integrated assembly that functions as one unit, eliminating the need for multiple separate disassembly steps while maintaining the ability to replace the entire assembly, thus improving user convenience while preserving adaptability

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention discloses an oval-shaped electronic cigarette and manufacturing process thereof. Inner housing of vaporization assembly is arranged inside outer housing of vaporization assembly and sleeved on vaporization assembly which comprises e-cigarette liquid cup and vaporizer having an outer wall in close fit with inner wall of the inner housing of vaporization assembly. A space is formed between outer wall of the e-cigarette liquid cup and inner wall of the inner housing of vaporization assembly to serve as a vapor flow channel. The inner housing of vaporization assembly is arranged at one end with vapor flow outlet, the outer edge of which is hermetically connected with and pressed against bell-mouth structure formed on the mouthpiece and made of soft material. The inlet opening formed on the outer housing of vaporization assembly, the air inlet arranged on the vaporization assembly where it is connected with the control assembly, the vapor flow vent hole formed on outer wall of the joint between e-cigarette liquid cup and vaporizer, the vapor flow channel formed by the space between inner housing of vaporization assembly and outer wall of e-cigarette liquid cup, the vapor flow outlet, and the channel arranged inside the mouthpiece, together constitute a continuous vapor flow pathway.
